Electronic devices such as household electrical appliances, meters, and clocks have many control functions, and therefore their outputs are used as channels for transmitting information between devices and users, such as letters and numbers. The aim is to make the electronic devices smaller and cheaper. However, there are high requirements for the display in terms of clarity and readability. continues to be imposed.

ものである。For example, three different display character types are used in the radio telephones manufactured by Applicant. The oldest is the seven-segment display, which allows numbers to be formed by linear elements in a well-known manner.

As discussed in detail below, most alphabetic characters can be satisfactorily formed using this method. In some devices, a 35-dot Ma) IJ sock mark is used, which produces beautiful letters of the alphabet, including lowercase letters.

アルファベット文字表示は、装置に新しい機能が急速に
導入されるにつれ、その重要さが増してきた。Alphabetic character displays have become increasingly important as new features are rapidly introduced into devices.

形状が数字でさえあっても容易に気付かないであろう。When using the known segment display or matrix display, a problem arises in displaying the current date and time. At present, many people are familiar with the 7-segment (Figure 1) digital clock, but some types of characters are different from other characters by just one element, which makes it difficult to read. somewhat limited in some respects. The line of a character is 24 times the area of its shape.
~82% is utilized, and in this case, the difference is obvious compared to the back side. In the 14 segments (Fig. 2), 7 more elements are added to the 7 segments, and one inertia of the character shape is broken. What's more, three elements in some corners and as many as eight elements in the center have to control one and the same point, but the ordinary eye cannot easily notice the shape, even if it is a number. Probably.

線の幅は、線の端部で狭くならねばならないので、その
文字の暗さは、その形の表面積の１５〜３０％である。The width of the line must be narrower at the ends of the line, so the darkness of the letter is 15-30% of the surface area of the shape.

アルファベット文字では、７セグメントの数字が示すの
と同じような馴れ易さという訳にはいかないのである。Alphabetical letters do not offer the same ease of familiarity that seven-segment numbers do.

１４セグメントは、市場におけるセルフサービスによる

量の表示においては、コントラストは、輝度に大きく影
響され、増大するのである。The 14 segments are visible to consumers only on self-service metering displays in the marketplace. In metric displays, contrast is greatly influenced and increased by brightness.

大抵のアルファベット文字は、形を推測して分るのであ
る。Most letters of the alphabet can be figured out by guessing their shapes.

７×、５マトリックス（第３図）は、非常に美しい数字

御が要求されるのである。However, it is difficult to display Scandinavian characters such as A, V, X, and Y. Even in these, matrix letters are familiar, for example on results boards. In this case, the adaptation range is better than 14 segments, 20 to 8
It is 0%. However, its shape is solid and clear. Therefore, although the symbol is physically weaker on a liquid crystal display, it is easily recognizable. Matrix requires more expensive electronic control than 7-segment or 14-segment displays.

FIG. 3 schematically shows the structure of a 14-segment display according to the prior art. FIG. 4 diagrammatically shows the structure of a 35-dot matrix according to the prior art. FIG. 1 represents the structure of a display matrix according to the invention. FIG. 5 is a comparison between displays obtained from various displays. As one of the preferred embodiments of the present invention, FIG. 1 shows an IJ Fuchs diagrammatic structure. A 16-dot matrix produces a satisfactory picture element in, for example, a liquid crystal display. The decisive novelty is that there are no restrictions on the shape of the picture elements.

いる。This display consists of a 3x5 matrix,
The present invention is provided in order to make the display difference between the letters M and N clear by dividing the picture element P5, which is the second from the top in the center column, into P5a and P5b. It is different from that. The basic shapes that have been familiar to us since the 7-segment have been preserved in numbers, and the image of alphabet letters has been promoted to make them easier to read.
I have tried to suit myself in the same way. The line width was large, where 34-80% darkness was obtained. This significantly improves readability in poor light.

1-34, using the same physical controls as in the 14-segment display. And even on the program side, changes are becoming less important. The 16-dot matrix display shown in FIG. 1 provides the character range shown in FIG. 5 at 50. Figure 5 shows 14 segments (Figure 5a) and 7x5
A comparison of character ranges for the matrix (FIG. 5b) and the matrix display according to the present invention is shown.

本発明によるマトリックス構造を用いることにより、記
号の読み易さは１４セグメントと比較しても、たとえ、
それが７×５マトリックスの品質の域には達していない
としても、実際的に改善されている。By using the matrix structure according to the invention, the legibility of the symbol is improved even when compared to 14 segments.
Even if it does not reach the quality of a 7x5 matrix, it is a practical improvement.

表示上生じる記号のより外部の外観を変更することが望
まれるときは、画要素は違った方法で形成されねばなら
ない。If it is desired to change the more external appearance of the symbol appearing on the display, the picture elements must be formed differently.

この場合、分割された画要素は、場所を決め、異った方
法で形づくられ得るのである。In this case, the divided picture elements can be located and shaped in different ways.
